An exact date wasn’t given, but the franchise will go in ground-floor space of the commercial and residential building at 336 Northampton St.

Cheeburger Cheeburger is known for letting customers “invent” their own burgers, choosing from five sizes, nine cheeses and more than 30 toppings.

Cheeburger Cheeburger has about 60 locations in 18 states. This will be the sixth in Pennsylvania and will have a 1950s-style decor. It will seat about 120 customers.

The franchise will be opposite Maxim’s 22, a French-style bistro that opened last year in the renovated Pomeroy’s building.

Developer Mark Mulligan said he’s been delighted by the progress.

“We’ve spent more than two years working on this building which had been vacant for more than 35 years,” he said in a prepared statement. “In that time we’ve seen an amazing movement in the city towards revitalization.”

The franchise plans to hire 40 to 50 full- and part-time workers, according to the Greater Easton Development Partnership.
